I am from the US, but I thought the winter wheel package was standard in Canada as well. Not sure if 2018 model year is different.
Sounds like your dealer needs to give you a free oil change for giving you the run around. The dealer is responsible for getting the package to your door mounted and balanced too. All 4 wheels and tires will fit in the back seat (up or down) if you want to pick them up yourself. There are door stickers and instruction sheet(s) and TPMS sensors on the pallet they come on.Thanks for the feedback! I sent Ford Canada an email regarding this, will also get in touch with the dealership too.
Will keep this threaded updated.
